New nuclear power in the UK: A strategy for energy security?

The aim of this paper is to explore the extent to which the construction of new nuclear power plants in the UK can safeguard or enhance energy security. The paper starts with a discussion of energy security, and breaks it down into four main categories of threat. These include threats due to fossil fuel scarcity and external disruptions, problems due to a lack of investment in infrastructure, threats due to technology or infrastructure failure, and risks due to domestic activism or terrorism. The paper then discusses one of the most common strategies put forward to improve security—the promotion of diversity within energy systems. Following this, the paper assesses the potential for new nuclear investment to ameliorate security threats in each of the four categories introduced earlier in the paper. The paper concludes that whilst nuclear investment can help to mitigate some threats to UK energy security, the government's case for supporting this investment ignores some equally important security issues. As a result, the energy security case for nuclear power has not yet been made.
